The RMF approach has been used to successfully describe masses and radii in stable nuclei [1]}, [2]}, [3]}
as well as to contribute to nuclear astrophysics problems [4]}, [5]}, [6]}, [7]}, [8]},
but it can also be extended for the explicit description of decaying resonances in exotic nuclei [9]}, [10]}, [11]}, [12]}.
Here, as mentioned above, couplings to continuum states are included in the Dirac equation using the CMR,
which is a particular case of Berggren basis [13]} built using spherical Bessel functions analytically continued in the fourth quadrant of the complex-momentum plane.
The idea is to represent the problem at hand in a basis including states having explicitly outgoing asymptotics,
so that its diagonalization provides eigenvectors whose asymptotics can be that of either a bound state, a scattering state, or a decaying resonance,
and its eigenvalues \(\tilde{E}\)  can be real \(\tilde{E} = E\)  or complex with \(\tilde{E} = E -i\Gamma /2\)  where \(E\)  is the energy position and \(\Gamma \)  the width of the resonance.
